Study Details

Study Description

Brief Summary

This study will examine the effects of co-administration of SPD489 and the antidepressant EFFEXOR XR on the pharmacokinetics of lisdexamfetamine, d-amphetamine, and EFFEXOR XR. In addition, serial blood pressure and pulse measures will be obtained and examined to ensure that there are no unexpected changes in vital signs following co administration of SPD489 and EFFEXOR XR that would impact the further study of this drug combination. The hypothesis is that a drug drug interaction could possibly exist.

    Primary Outcome Measures

    1. Maximum Plasma Concentration (Cmax) of Lisdexamfetamine Dimesylate [Day 15 and Day 30 (24 hour sampling)]

      Lisdexamfetamine dimesylate (SPD489) itself is inactive, but following oral administration is converted to the active isomer, d-amphetamine, that is responsible for the drug's therapeutic activity.

    2. Cmax of d-Amphetamine [Day 15 and Day 30 (24 hour sampling)]

      d-Amphetamine is the active isomer of Lisdexamfetamine dimesylate (SPD489) and is responsible for the drug's therapeutic activity.

    3. Cmax of Venlafaxine Hydrochloride [Day 15 and Day 30 (24 hour sampling)]

      Venlafaxine Hydrochloride is the active ingredient of Effexor XR

    4. Cmax of o-Desmethylvenlafaxine [Day 15 and Day 30 (24 hour sampling)]

      Venlafaxine, after oral administration, is metabolized in the liver to an active metabolite, o-Desmethylvenlafaxine.

    5. Cmax of Composite (Venlafaxine + o-Desmethylvenlafaxine) [Day 15 and Day 30 (24 hour sampling)]

    11. Time of Maximum Plasma Concentration (Tmax) of Lisdexamfetamine Dimesylate [Day 15 and Day 30 (24 hour sampling)]

    12. Tmax of d-Amphetamine [Day 15 and Day 30 (24 hour sampling)]

    13. Tmax of Venlafaxine Hydrochloride [Day 15 and Day 30 (24 hour sampling)]

    14. Tmax of o-Desmethylvenlafaxine [Day 15 and Day 30 (24 hour sampling)]
